(PC) Death end re:Quest 2 .DAT files

[GabryTheSniper]

While digging through the game files, i came across these files: GxArchivedFile001.dat , GxArchivedFile051.dat . Is these a way to decompile them with a script? 

Here's the sample if you want to take a look: https://drive.google.com/file/d/1fKPt0HOZa0qsfX9x1Wqh22OuauA5hG8V/view?usp=sharing

Do i have to use 010 Editor to run it?

Yes, but you can also rewrite it to the bms form.

Well he we go. But not sure how to reverse extension order for example "xet" > "tex" so extensions will be in reversed order. Nothing cardial...

Also no file names either. I bind offset as a file name.
